Composition resistors are considered one of the most reliable of all

electronic components. There are no windings or film, resulting in a

non-inductive resistor with excellent surge and high frequency char-

acteristics. The parts are also utilized in fusing applications. Hi-Rel

Group A or A&B Screening per Mil-R-39008 is available.

protoypes under worst case conditions. Consult factory for assistance on all surge and fusing applications.

APPLICATION GUIDE

(refer to R-46 guide for additional info)

CC’s are often utilized in high frequency, fusing or pulse applications, including snub-

bers, lightning surges, grounding resistors, RFI suppression, etc. Depending on the ap-

plication, CC’s can often satisfy requirements of GR1089, ITU-K20, IEC61000-4-x, etc.

For fusing applications, use the peak pulse rupture voltage graphs and energy ratings as

a rough starting point to determine typical fusing levels. For surge applications, employ a

minimum 50% derating (greater for multiple surges, elevated temperatures, etc.). Fusing

and surge capability can vary fairly significantly so be sure to consult RCD on applica-

tions that involve any surges or fusing, and verify selection by evaluating under worst

case conditions. Series CC resistors are not intended for life-support applications.

Composition construction isn’t as stable as other types of resistors, especially in humid

conditions, and therefore not suitable for precision applications (refer to RCD’s PR and

CFZ Series for improved stability). In accordance with MIL-R-39008, parts that have

shifted beyond the nominal tolerance due to moisture shall be baked by the user at

100°C to recondition the resistance value back into tolerance.
